| Abstract |
The purpose of these investigations, which were carried out on rabbits, was to study the effects of helium-neon and YAG (yttrium-aluminium-garnet) laser radiation on the retina at levels capable of disturbing retinal function without producing gross pathological manifestations (i.e. lesions which can be observed with the ophthalmoscope). The techniques used include electroencephalography, light microscopy, electron microscopy and autoradiography. The existence of subvisible lesions was established at exposure levels corresponding to 50% of the visible lesion exposure threshold. YAG laser exposure produced unexpected increases in the amplitude and duration of EEG potentials, a result which has not been explained. Subvisible lesions appear to be reversible. |
